The machine terminal measures the analog signals needed for protection, measurement, etc. Via sensors or galvanically separated matching transformers. The machine terminals can be provided with the following matching transformers:

• 5 current and 4 voltage transformers:

CT1, CT2, CT3, CT4, CT5, VT1, VT2, VT3, VT4

• 6 current and 3 voltage transformers:

CT1, CT2, CT3, CT4, CT5, CT6, VT1, VT2, VT3

• 7 current and 2 voltage transformers:

CT1, CT2, CT3, CT4, CT5, CT6, CT7, VT1, VT2

• 8 current and 1 voltage transformers:

CT1, CT2, CT3, CT4, CT5, CT6, CT7, CT8, VT1

 

In addition to conventional matching transformers, current sensors and voltage dividers developed by ABB can be used in the machine terminals. The machine terminal has 9 sensor inputs. A current sensor (Rogowski coil) or a voltage divider can be connected to each sensor input. The machine terminal allows the user to configure each sensor input for the type of sensor to be used. Furthermore, the machine terminal is provided with general measurement via sensor inputs. This allows, e.g., temperature monitoring, provided a temperature sensor with a voltage transducer output is available.

 

The third letter in the four-letter extension of the order number specifies whether the machine terminal is to be equipped with conventional matching transformers or with matching transformers and sensor inputs.
